RDMA/nes: Remove session_id from nes_cm stuff
The session_id members of struct nes_cm_listener and struct nes_cm_node are write-only, so remove them. This allows the session_id member of struct nes_cm_core to be removed as well, since it is only used to write those other session_id values. This removes the use of current->tgid (which will be deprecated) pointed out by Pavel Emelyanov <xemul@openvz.org>. Acked-by: Glenn Streiff <gstreiff@neteffect.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
